Cleaning composition



Patented June 16, 1936 UNITED STATES PATENT OFFICE No Drawing. Application November 23, 1932, Serial No. 644,078

The present invention relates, generally, to a cleaning composition for use with or without water; and, more particularly, the present invention relates to cleaning compositions adapted 6 to emulsify quickly with water and to be easily rinsed or washed off with water.

An object of the present invention is to provide a cleaning composition in liquid form which emulsifles easily and quickly with water and 10 which can be used with or without water for various purposes such as cleaning clothing, carpets, and the hands, automobile bodies and other painted or lacquered surfaces, for the de-gumming of silk, wool and so on after weaving and 16 which can be easily and completely washed off after the cleaning process.

Another'object of the invention is to provide a cleaning composition for removing dirt and grease.

90 Other objects and advantages of the present invention will be apparent from the following disclosure and from the accompanying claim.

The cleaning composition of the present invention comprises essentially the following in- 95 gradients, each having a purpose or function as hereinafter set forth: water, soap and sulfonated vegetable oil, hydrocarbon chloride, petroleum spirit and trisodium phosphate. The water is used as a solvent for the soap. The soap serves,

30 among other functions, to form a film or scum on the surface of the applied composition to prevent evaporation of the hydrocarbon chloride and the petroleum spirit. The hydrocarbon chloride serves for cutting grease and dirt in the 35 cleansing operation. The petroleum spirit also serves to dissolve greases and cut dirt and further serves to protect the hands, paint and varnish surfaces and so on toning down the action of the hydrocarbon chloride and restricting the action 40 of the latter to the dissolving of grease. The sulfonated oil facilitates the formation of an emulsion of the ingredients named, particularly on the addition of water in a small or large quantity during the application of the composition 5 and during the rinsing or washing of the composition from the clean surface or body. The trisodium phosphate increases the rinsibility of the composition from the washed surface, fabric, and so on by softening the water.

50 The mixture of these ingredients is usually cloudy, the ingredients separating into layers. The cleaning composition can be used in this state, intermixture being obtained by occasional shaking. To produce a permanently unclouded 55 mixture or solution I add a small quantity of an organic material having an unsaturated carbon conjugation such as oleic acid, red oil, white oleicacid, pine oil, rosin oil, rosin, cotton seed oil or facts, and so on. To get a clear, light colored mixture or solution I use pine oil or white 5 oleic acid. The free fatty acid material can be added after all the other ingredients are put together and is added in small quantities until the mixture clears up to the appearance of a clear solution. With white oleic acid about 10 eight fluid ounces, more or less, are required to clear five gallons of the mixture of ingredients, the exact amount depending on the source and state of the ingredients because of variations in materials from different commercial sources and I5 batches. -As the mixture clears up it thickens to a good body but not of too high viscosity. The free fatty acid can be still added, after the clear and bodied state has been reached, through a small practical range after which further addi- 2 tion of fatty acid causes cloudiness which is' accompanied by a loss of body or thinning of the liquid and a separation to a state similar to that in which it was ,before any fatty acid was added. The amount of free fatty acid necessary 25 is about to 2%%, more or less, for example, depending on the actual ingredients used and the quantities of each used. The petroleum spirit can be gasoline, kerosene, crude oil, fuel oil and so on; and the hydrocarbon chloride can be 30 carbon tetrachloride, trichlorethylene and so on.

Example 1.-.An example of the composition of the present invention is as follows, the proportions of the ingredients being given in parts by weight: soap about 5 parts, water about 35 to parts, Turkey red oil (75%) about 15 to parts, trichlorethylene about 20 to parts, petroleum spirit about 25 to 50 parts and trisodium phosphate about 2 parts, and suiilcient pine oil to clarify the mixture, say about l of the rest of the composition. The composition of this example is suitable for general use.

Example 2.-An example of a composition for use for washing automobiles, buses or other painted or varnished surfaces is as follows: wa-

ter 12 parts, soap about 5 parts, Turkey red oil (75%) about 25 parts, trichlorethylene about 35 parts, kerosene about 35 parts and trisodium phosphate about 2 parts, and suiiicient pine oil to clarify the mixture, say about 1%% of the rest of the composition.

Example 3.An example of the composition of the present invention to be used as a liquid hand soap is as follows: water about 12% parts, soap about 5 parts, Turkey red oil about 25 parts,

trichioretiulene about 20; parts; kerosene about -suiilcient white oleicacid or pine oil to clarify .sitionoi Example 1 is mixed with ac to 25 vol- 1 7 umes of water, an emulsion, being formed im :mediateiy and the am unt of water determined 7 4 by the condition of the to be cleaned:
